The slope is 1.
Step-by-step explanation:
Answer:
The first number in each ordered pair tells how far across the X line is to move. The second number in each ordered pair tells how far up or down the Y line is to move. The point where the X and Y lines cross is marked “0” on the graph. It is called the “origin,” and is the starting point for plotting points.
First, you find out how much can be filled in 1 minute. Then you divide that into 120 to get your answer.
To find out how much can be filled in 1 minute, take the time and divide it into the volume. We'll use the second row (2 minutes and 8 gallons.)
8/2=4. So it takes 1 minute to fill 4 gallons. Now, you just divide 4 into 120.
120/4=30
It takes 30 minutes to fill the pool up to 120 gallons.
Answer:
Step-by-step explanation:
take angle U as reference angle
using sine rule
sin U=opposite /hypotenuse
sin U=42/42
sin U=1
sin 90=1
therefore angle U=90 degree
Going from (-4,5) to (3,-2), x increases by 7 and y decreases by 7; thus, m = -7/7 = -1.
